BOTTLE-CLEANING MACHINE.

Specification of Letters Patent. Patented Dec, 28, 1909, Application filed April 9, 1909.

Serial No. 488,943.

To all whom 'it may concern:

Be it known that I, ANDERS ANDERSEN PrNDs'ror'rn, manufacturer, a subject of Denmark, residing at No. 62 Frederiksberg, in the city of Frederiksberg, near Copenhagen, and Kingdom of Denmark, have invented new and useful Improvements in Bottle- Cleaning Machines, of which the following is a specification.

The invention relates to a continuously working rotary bottle cleaning machine, which simultaneously scrubs and cleans the inserted bottles both on the inner and the Iouter side.

The machine works with great rapidity and only one attendant is needed, who with one hand inserts the bottles to be cleaned and with the other hand takes off the cleaned bottles.

The machine is characterized by a number of horizontal brush-spindles which clean the inner side of the bottles and which are radially arranged around a rotary vertical shaft from which the brush-spindles are rotated, further by means by which all the brush-spindles are moved around said vertical shaft in such a manner that the bottles can be inserted upon and taken off from the brush-spindles at the same place. Further the machine is characterized by means by which said movement of the brush-spindles around the vertical shaft is automatically stopped if bottles are not inserted upon the brush-spindles, and further by a number of bottom-brushes, one for each of the brushspindles, which are automatically pressed against the bottom of the bottle, when the cleaning commences and again automatically thrown back when the bottle shall-be taken oi.

The machine is further characterized by the provision of one or more scrubbing devices arranged above the brush-spindles which scrubbing devices clean the outside and neck of the bottles, and which for instance can be one or more cylindrical brushrollers placed in such a manner that theline of intersection between a vertical plane through their axis and a horizontal plane through the axis of the brush-spindles will i he a chord to the circle described by the ends of said brushespindles, as by such an arrangement the entire exterior surface of diameter of the middle part of said brushroller is greater than the diameter of its two ends as thereby the scrubbing effect upon the neck of the bottles and upon the part connecting the neck and the body of the bottles is improved. Further, the machine is characterized thereby that each of the brush` spindles with its appurtenance is mounted in a special bearing loosely mounted in the rotary frame carrying all the brush-spindles, which arrangement permits that all of said brush-spindle systems can be removed and inserted independently of each other.

Other characteristic features of the machine will appear from the following description and from the drawings which illustrate a constructional form of a machine arranged in accordance with the invention.

Figure l is a vertical middle section of the machine taken on the line A-A Fig. 2. Fig. 2 is a plan of the machine; the driving` members upon the upper part of the vertical shaft are omitted. Figs. 3 and 4L show one of the loose brush-spindle systems respectively in vertical middle section and in plan. Around the vertical shaft a, the lower end of which is supported in the stationary frame Z) and which by means of the gea-ring c, Z is rotated from the driving shaft c, is arranged a number of radial, horizontal brush-spindles the bearings g of which are loosely and oscillatorily inserted in a rotary frame 7L, which rests loosely upon the toothed wheel c' rotated by a worm 7a fixed to a constantly rotated shaft j. The friction caused by the pressure of the frame t upon the toothed wheel z' normally causes that the frame 7L is rotated around thefshaft s together with the wheel z'. Upon the shaft a is further fixed a friction disk Z against which the friction rollers m of the brushspindles are pressed by the weight of the bottles inserted upon said brush-spindles, so that in such case the brush-spindles are rotated when the shaft a is rotated. When the bottles are removed from the brushspindles no pressure will keep the rollers m in frictional Contact with the friction disk Z and consequently the rotation of the brushspindles will cease until bottles again are inserted upon the brush-spindles. The friction-disk Z can be replaced by a toothed wheel in which case the friction-rollers m are replaced by pinions.

ln frontof each of the brush-spindles is arranged a revoluble bottom-brush ift-provided with studs l and 2. Then the machine rotates in the direction of the arrow (Fig. 2) the stud l takes against a stud 29 fixed to the frame of the machine, thereby turning the bottom-brush against the bottom of the bottle inserted upon the corresponding brushspindle whereupon said bottom-brush is kept in this position during the cleaning by the circular edge r of the stationary frame. Then the cleaning is completed the stud 2 takes against a second stud 0 fixed to the frame b, thereby turning back the bottom brush so that the bottle can be removed. In front of each brush-spindle is further arranged a revoluble arm s provided with a recessed guide-funnel z5, which normally is situated in front of the end of the brushspindle and which has for its object to guide the mouth of the bottles during the insertion upon the brush spindles. The arm s is further provided with a stud u, which takes against the fixed stud 79 and stops the movement around the shaft a of the frame 7L if the arm s is not previously turned bacl; by hands or by insertion of a bottle upon the brush-spindle.

Above the brush-spindles is mounted a brush-roller o, which rotates around a horizontal shaft and being arranged in such a manner that the line of intersection between a vertical plane through its axis and a horizontal plane through the axis of the brushspindles is a chord to the circle described by the ends of said brush-spindles. The diameter of the middle part of said brush-roller is greater than the diameter of its two ends.

The bottles are supported by and roll upon a bottle-support m, which can be rotated by means of the worm y, z; the bottlesupporting edge of said bottle-support fc can be adjustable and its upper surface can be corrugated.

The working of the machine is the following: The attendant, who is placed in front of the machine, inserts the bottles upon the brush-spindles, when they are in the posi.- tion C (F ig. 2) and removes the cleaned bottles from the brush-spindles when they are in the position C. During the passagethrough the machine the inner side of the bottles is treated by the brush-spindles f and the outer side by the bottoni-brushes yn and the scrubbing-apparatus or brush-roller o which owing to its special position will thoroughly clean the out-side of the bottles from one end of the bottles to the other.
